sunjincheng commented on IOTDB-1143: ------------------------------------ Thanks for your proposal [~songbinghua]! CQ is nice feature for IoTDB,would be great if there is any detail design to share? > continuous query > ---------------- > > Key: IOTDB-1143 > URL: https://issues.apache.org/jira/browse/IOTDB-1143 > Project: Apache IoTDB > Issue Type: New Feature > Components: Core/Engine > Reporter: songbinghua > Assignee: songbinghua > Priority: Blocker > > Continuous Query is a very useful feature for users to query time series data > periodically according to the time interval and time range. > For example, using the continuous query described below, the IoTDB > downsamples the CPU load metric, and keeps a single average datapoint per 15 > minutes grouped by server region: > CREATE CONTINUOUS QUERY "downsampled_cpu_load" > ON database_name > BEGIN > SELECT mean(value) as value, > INTO "downsampled.cpu_load" > FROM cpu_load > GROUP BY time(15m), region > END > However, the IoTDB does not yet support this feature,but the InfluxDB has > supported this feature and many scenario need this feature eagerly. So we > need to support Continuous Query,and I would like to develop it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
